"This session (which will be presented at iPad Summit and Region 20 Tech Fiesta) focuses on how elementary teachers can use a single iPad productively:
in multiple settings and configurations such as whole group, pass around, small groups, and stations
using both consumptive and product-based apps
showcasing actual student work and app-tivities across the curriculum"
YouTube has a feature called Annotations which allows you to create links from one video to multiple others. You can use this feature to create a sort of interactive navigation path through a series of videos. The whole process allows for a lot of interesting possibilities; such as interactive games, story telling, training sequences, or product overviews.
